Fuel to the engines of the Air India plane that crashed last month appears to have cut off shortly after take-off, a preliminary report has found.

According to the report by India's Aircraft Accident Investigation Bureau (AAIB), switches in the Boeing 787 Dreamliner's cockpit that controlled fuel moved to a "CUTOFF" position.

It said: "Engine 1 and Engine 2 fuel cutoff switches transitioned from RUN to CUTOFF position one after another with a time gap of one second.

"The Engine N1 and N2 began to decrease from their take-off values as the fuel supply to the engines was cut off."

There was then confusion in the cockpit. In the voice recording, one of the pilots is heard asking the other why he "cut off". The other pilot responds that he did not do so.

The 15-page report did not identify which comments were made by the flight's captain and which were made by the first officer. One of the pilots made a "mayday, mayday, mayday" call just before the crash.

Both pilots were experienced, with around 19,000 flying hours between them, including more than 9,000 on the 787.

Flipping to cutoff almost immediately cuts the engines, and is most often used to turn the engines off once a plane has arrived at its airport gate and in certain emergency situations, such as an engine fire - though both switches together are rarely used simultaneously.

The report does not indicate there was any emergency requiring an engine cutoff. It also does not give a conclusion as to how the switches moved.

However, aviation expert David Learmount told Sky News "it sounds deliberate", but also noted "there are cases of pilots carrying out an incorrect action instead of what they should be doing".

Mr Learmount said the only action the pilots needed to conduct at the time was retracting the plane's undercarriage, but this was not done.

He added: "Was that it? These switches are nowhere near the undercarriage lever and look totally different. The fuel switches cannot be turned on or off by mistake. They have to be pulled out before selecting up (run) or down (cut off)."

Similarly, Tim Atkinson, a pilot and aviation consultant, told Sky News' Gillian Joseph "there are very few situations or circumstances which would explain this"

He explained: "One would be an utterly extraordinary human error, an unintentional act, and the other - I'm very sorry to say - would be an intentional act. And that's not a suggestion or allegation, it's simply an analysis of the small amount of information that we have at hand at this moment."

One of the engines was able to be restarted, but could not reverse the plane's deceleration, the report found.

India's AAIB said in its report: "At this stage of investigation, there are no recommended actions to Boeing 787-8 and/or GE GEnx-1B engine operators and manufacturers."

No significant bird activity was observed in the vicinity of the plane's flight path, the report said. The aircraft started to lose altitude before crossing the airport perimeter wall, it added.

The plane plummeted into a busy area, killing 241 passengers and 19 others on the ground while incinerating everything around it.

The only surviving passenger was Briton Vishwash Kumar Ramesh, who was sitting next to an emergency exit and, according to police, "managed to escape by jumping out the emergency door".

The plane crashed and struck a medical college hostel in a residential part of Ahmedabad, with the report stating: "The aircraft was destroyed due to impact with the buildings on the ground and subsequent fire."

The plane's two black boxes, which combined cockpit voice recorders and flight data recorders, were recovered in the days after the crash.

They provide vital data such as altitude, airspeed and final pilot conversations, which can help narrow down the possible causes behind a crash.

The AAIB's report is based on the initial findings of the probe, marking 30 days since the crash. It said the investigation is continuing. A final report is expected within a year.

Maybe they were never put ON from
The aircraft’s last flight! This like turning off your fuel switch on generators. But it will start in the next time you put it ON. But will go off after some some seconds because the fuel switch wasn’t turned ON for flow of fuel.

The maintenance crew of that aircraft should be investigated, to get to know the truth. There might be an important person or two in that aircraft who people of interests to other people, there is a conspiracy!

Just my personal opinion.

Not to sound insensitive, but the only survivor has some questions to answer, it sounds fishy how he plotted his escape

Was he the pilot?

Was he the one in the cockpit? So eOne managed to escape and you are saying something else

Really

Was he the one in the cockpit?

Is he the one that gave himself the seat near the emergency exit?

Was the fuel on and off power/ switch be controlled from where he sat?

Learn how to think next time

A lot of people on social media these days actually talk more nonsense than making sense.

This guy Yiu quoted is talking BS.

The Black box was found and the voice recorders already said that the fuel supply ti the two engines were cut off and only a human being can turn the switch off, either deliberately or in error.

How's that the concern of a passenger in economy class?
